Mercator Projection Distortions

Comments center on the distortions introduced by the Mercator projection in world maps, particularly exaggerating sizes of polar regions like Greenland and Antarctica, and discussions of alternative projections or preferring globes.

It's Mercator you know. We're just used to the distortions the other way up. :-)

It's the Mercator projection's fault

I'd love to see this on a globe rather than a Mercator projection.

Ah, this makes sense. I'm thinking of the Mercator projection of the globe.

Is your globe showing a Mercator projection??https://xkcd.com/977/

You are measure a 3d projection on a 2d plane. There has to be distortion somewhere. Most likely they use the mercator projection which has places further from the equator appear bigger than the ones near the equator.

You are missing the nuances of various map projections[0], perhaps.[0] https://en.wikipedia.org/wiki/Map_projection

This is not a good use case for the Mercator projection.Mercator sacrifices area accuracy to facilitate navigation.

The Mercator projection is useful to navigators on high seas, but nowadays, that's just irrelevant. De-zoom and look at the size of Groenland or Antarctica to see :)

Most likely a result of the flaws of the Mercator projection (https://en.wikipedia.org/wiki/Mercator_projection#Mathematic...).
